It’s not a specific release date, but the Apple Watch now has a slated month for its release.

Per Macworld, Apple CEO confirmed that the Apple Watch will begin shipping in April. Cook dropped the news on Apple’s quarterly earnings call Tuesday afternoon, saying Apple Watch is “on schedule” and will ship in April. The company reportedly hasn’t publicly committed to a date because Cook and co. are still working on the device’s battery life.

According to recent reports, Apple is aiming for 19 hours of mixed active and passive use, but isn’t sure it can nail that goal for the first generation of Apple Watches.
